摘要： The present invention is directed to a method and system of processing and removing hydrocarbon sludge from a tank wherein the hydrocarbon sludges are the product of gravity settling in the bottom of the tank to form a sludge consisting of inorganic and organic materials not readily flowable or pumpable for removal in the found state and where a process is used to selectively separate, grind, disperse and suspend these materials with a mechanical classifier system, and where flow agents may be metered to effect a slurry stream directed thru a nozzle system towards the sludge in the tank and by reducing the surface tension and mechanical conditioning of the sludge, create a pumpable slurry that may be removed from the tank with minimal time, cost and environmental impact.

摘要： Systems for cleaning sludge from a large tank. The sludge from the interior of storage tanks is mobilized using a metered flow agent stream and then subjected to a mechanical comminution or high shear action, e.g. by grinding or chopping. This produces a pumpable slurry which is then recirculated back into the tank to further mobilize sludge.

摘要： Methods and systems for operating a facility which stores large quantities of petroleum. When the large storage tanks need cleaning or sludge abatement, the sludge from the interior of storage tanks is mobilized using a metered flow agent stream, and then subjected to a mechanical comminution or high shear action, e.g. by grinding or chopping. This produces a pumpable slurry which is then recirculated back into the tank to further mobilize sludge. This cleaning technique results in a faster cleaning process. This also provides a process which is less exposed to uncertainties in the composition of the sludge, e.g. to how much rust or scale is present in the sludge. Since the duration of downtime for cleaning is shorter AND less uncertain, tank cleaning can be scheduled into smaller schedule gaps, resulting in less capital cost (for downtime) and lower maintenance budget overall (since developing leakage problems can be caught sooner). This process also reduced discharge, and hence imposes less environmental burden. This means that the facility as a whole provides more environmentally friendly operation.
摘要翻译：操作储存大量石油的设施的方法和系统。当大型储罐需要清洁或污泥消除时，来自储罐内部的污泥使用计量流动剂流动起来，然后进行机械粉碎或高剪切作用，例如，通过研磨或切碎。这产生可泵送浆料，然后将其再循环回罐中以进一步调节污泥。这种清洁技术导致更快的清洁过程。这还提供了一种较少暴露于污泥组成的不确定性的方法，例如，污泥中存在多少锈或垢。由于清洁停机时间较短且不太确定，因此油罐清洁可以安排在较小的进度空白中，从而减少投资成本（停机时间），并降低整体维护预算（因为开发泄漏问题可能会更早发生）。这个过程也减少排放，因此施加较少的环境负担。这意味着整个设施提供更环保的操作。
